Workflow – the interface is designed to support a workflow similar
to reading network news or mail. In particular, it is designed to
deal with a large number of review requests across a large number
of projects.

Offline Use – Gertty syncs information about changes in subscribed
projects to a local database and local git repos. All review
operations are performed against that database and then synced back
to Gerrit.

Convenience – because Gertty downloads all changes to local git
repos, a single command instructs it to checkout a change into that
repo for detailed examination or testing of larger changes.

Installation

It is recommended (but not required) to install Gertty in a
virtualenv. To do set one up:

virtualenv gertty-env
source gertty-env/bin/activate

To install the latest version from the cheeseshop:

pip install gertty

To install from a git checkout:

pip install .

Gertty uses a YAML based configuration file that it looks for at
~/.gertty.yaml. Several sample configuration files are included.
You can find them in the examples/ directory of the source
distribution or the share/gertty/examples directory after installation.

Select one of the sample config files, copy it to ~/.gertty.yaml and
edit as necessary. Search for CHANGEME to find parameters that
need to be supplied. The sample config files are as follows:

minimal-gertty.yaml

Only contains the parameters required for Gertty to actually run.

reference-gertty.yaml

An exhaustive list of all supported options with examples.

openstack-gertty.yaml

A configuration designed for use with OpenStack’s installation of
Gerrit.

You will need your Gerrit password which you can generate or retrieve
by navigating to Settings, then HTTP Password.

Gertty uses local git repositories to perform much of its work. These
can be the same git repositories that you use when developing a
project. Gertty will not alter the working directory or index unless
you request it to (and even then, the usual git safeguards against
accidentally losing work remain in place). You will need to supply
the name of a directory where Gertty will find or clone git
repositories for your projects as the git-root parameter.

The config file is designed to support multiple Gerrit instances. The
first one is used by default, but others can be specified by supplying
the name on the command line.

Usage

After installing Gertty, you should be able to run it by invoking
gertty. If you installed it in a virtualenv, you can invoke it
without activating the virtualenv with /path/to/venv/bin/gertty
which you may wish to add to your shell aliases. Use gertty
--help to see a list of command line options available.

Once Gertty is running, you will need to start by subscribing to some
projects. Use ‘L’ to list all of the projects and then ‘s’ to
subscribe to the ones you are interested in. Hit ‘L’ again to shrink
the list to your subscribed projects.

In general, pressing the F1 key will show help text on any screen, and
ESC will take you to the previous screen.

Gertty works seamlessly offline or online. All of the actions that it
performs are first recorded in a local database (in ~/.gertty.db
by default), and are then transmitted to Gerrit. If Gertty is unable
to contact Gerrit for any reason, it will continue to operate against
the local database, and once it re-establishes contact, it will
process any pending changes.

The status bar at the top of the screen displays the current number of
outstanding tasks that Gertty must perform in order to be fully up to
date. Some of these tasks are more complicated than others, and some
of them will end up creating new tasks (for instance, one task may be
to search for new changes in a project which will then produce 5 new
tasks if there are 5 new changes). This will explain why the number
of tasks displayed in the status bar sometimes changes rapidly.

If Gertty is offline, it will so indicate in the status bar. It will
retry requests if needed, and will switch between offline and online
mode automatically.

If Gertty encounters an error, this will also be indicated in the
status bar. You may wish to examine ~/.gertty.log to see what the
error was. In may cases, Gertty can continue after encountering an
error. The error flag will be cleared when you leave the current
screen.
